DIE FOR SHEET-METAL MANTELS.

SPECIFICATION forming part of Letters Patent No. 539,896, dated May 28, 1895.

Application filed May 18, 1894.

To aZZ whom it may concern.-

Be it known that I, JOHN GRAVES, a citizen of the United States, and a resident of Brooklyn, in the county of Kings, State of New York, have invented a certain new and useful Improvement in Dies for Sheet-Metal Mantels,

, of which the following is a specification.

My invention relates to improvements in dies for sheet metalmantels, and it especially consists in providing the dies with interchangeable parts, whereby different designs can be produced by means of the same die, by merely changing the certain parts thereof.

Heretofore the dies for stamping sheet metal mantels have been made substantially solid in all parts and unchangeable, so that as many dies have been required as there are designs of mantels; but as the dies are quite expensive, a plant for producing various designs of mantels has required a large outlay of money, and the interest on the plant and the wear and tear thereof have been equivalent to a considerable increase in the cost of the mantel. I have however invented dies with interchangeable parts, which parts are adapted to be readily inserted in the body of I the die, and removed therefrom, the insertion V the specification to aid the description, Figure l is a longitudinal section of the male and fe male members of a die, taken through the parts thereof which produce the frieze of the mantel. Fig. 2 isalongitudinal section of the same, but taken through the parts thereof which form the pilasters. Fig. 3 is avertical section of the same, taken through one of the panels of the frieze. Fig. 4 is a plan View of the male die.

A is the male and B the female die. Referring to Fig. 1, a a produce the wall plate of the mantel, b b profiles, and c c the frieze.

Serial No. 511,658. (No model.)

Referring to Fig. 2, d d and e e produce the pilasters.

Now the frieze ofa mantel usually contains panels, and a mantel which has the said panels raised presents a very different appearance from one in which the said panels are sunk. I arrange my die to produce both styles of design with little change in the die, by providing panels 9 g,'h h respectively in the male andthe female dies. Said panels 9 g, 7th are each nicely fitted into recesses in their corresponding diesA,B,and may be secured therein by screws .9 as indicated. In the arrangement shown in Fig. 1, said panels 9 g are a little lower than the general surface of the die A, and said panels h hare a little higher than the general surface of the die B, and thus arranged said dies A, B, will produce a mantel having sunken panels in the frieze. To produce a mantel with raised panels in the frieze, the aforesaid panels g g, h It will be respect ively transferred to the dies B and A. Evidently the working surfaces of said panels g g, h h can have Various ornamentations thereon such as flutings. Then, by placing other 'panels, with other arrangements of fluti-ngs, in the place of said panels, 9 g, h h, the ornamentation of these parts of the mantel will be changed. Moreover if we suppose, for example, that the panels g 9 have grooves and the panels h h, beads or ribs corresponding to the grooves, it is evident that a different efiect may be given to. the ornamentation by simply transferring the panels 9 g to the female die B, and the panels 72. h to the male die A; also by placing in both dies A B panels which are flush therewith a mantel would be produced having a plain frieze without panels.

Referring to Fig. 2,7' j are vertical panels in the male die A, and kit are corresponding panels in the female die B, and which panels together form the ornamentation of the pilasters. Said panels jj, is k are fitted into corresponding recesses in the dies A, B respectively, and are held thereinby screws t. When arranged as shown the said panelsjj, 7.0 lowill produce sunken pilasters. To produce raised pilasters the panels jj willbe transferred to the die B, and the panels 70 is to the die A.

The vertical panels Z I (Fig. 2) are intended to produce different styles of facings, and said panels Z Z are required on only one of the dies at one time. When said panels Z Z are arranged on the depression 19 of the male dies in the manner represented in Fig. 2, a plain facing is produced, and the mantel is termed a Shang-Hai mantel. WVhen said panels Z Z are transferred to corresponding parts of the die B, a mantel having a return and a sunken facing will be produced. It will be understood that the metal of the mantel, which extends between said panels ZZ, (Fig. 2) is usually out out after the mantel is stamped, and a summer piece inserted in the opening.

The horizontal panel n (Fig. 3) corresponds in its function and purpose to the panels Z 1 (Fig. 2) and when a Shang-Hai mantel is to be made said panel at is applied to the male die A as shown. When a mantel with a return and a sunken facing is to be made, said panel n is transferred to the corresponding part of the female die B.

I prefer to round off the corners of the re- In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 14th day of February, 1894c.
